Moduli-Space Dynamics of Noncommutative Abelian Sigma-Model Solitons
Michael Klawunn, Olaf Lechtenfeld, Stefan Petersen
In the noncommutative (Moyal) plane, we relate exact U(1) sigma-model solitons to generic scalar-field solitons for an infinitely stiff potential. The static k-lump moduli space C^…

Sigma-Model Solitons in the Noncommutative Plane: Construction and Stability Analysis
Andrei V. Domrin, Olaf Lechtenfeld, Stefan Petersen
Noncommutative multi-solitons are investigated in Euclidean two-dimensional U(n) and Grassmannian sigma models, using the auxiliary Fock-space formalism. Their construction and mod…
